Description

Technical Field

[0001] This utility model relates to the field of dental implant technology, and in particular to a composite dental implant component. Background Technology

[0002] When teeth are missing, a surgical procedure is performed to implant an artificial tooth root, known as an implant, into the alveolar bone. After 3 to 6 months, a porcelain crown, or porcelain-fused-to-metal crown, is then placed on top of the implant; its material is identical to that of a natural tooth. A significant problem with current dental implants is that the stress concentration point is located at the interface between the alveolar bone and soft tissue. Over prolonged use, this can lead to a series of adverse consequences. Because the stress is concentrated at this interface, it continuously affects the alveolar bone, causing the alveolar bone level to gradually decrease. This decrease in alveolar bone level directly impacts the stability of the dental implant, reducing its overall stability. Therefore, improvements are needed to address these issues.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0018] Example: See Figure 1-4This invention discloses a composite dental implant component, comprising a crown 1, a connecting groove on the bottom surface of the crown 1, and a connector 3 at the lower end of the crown 1, the connector 3 being placed within the connecting groove; the connector 3 facilitates the installation of the crown 1; multiple equidistant titanium alloy skeletons 5 are fixed to the periphery of the bottom surface of the connector 3, the transverse joint surfaces of the titanium alloy skeletons 5 are arc-shaped, and the inner surfaces of the multiple titanium alloy skeletons 5 are provided with threaded grooves; the titanium alloy skeletons 5 facilitate the installation of the connector 3, and the arc shape of the titanium alloy skeletons 5 facilitates conforming to the alveolar bone; the outer surface and sidewalls of the titanium alloy skeletons 5 are coated with a hydroxyapatite coating 6; the hydroxyapatite coating 6 facilitates faster fusion of the titanium alloy skeletons 5 with the newly formed tissue. The crown 1 has a mounting groove 2 on its top surface, and a through hole on the bottom surface of the mounting groove 2. The connector 3 has a mounting hole on its top surface, and a fixing bolt 4 is installed in the mounting hole. The fixing bolt 4 is threadedly connected to the titanium alloy skeleton 5.
